You'd just be silly to write him off so soon. New league, new club, still quite young.
I know almost nothing about the guy save a few highlight reels. He doesn't seem to me at all like a regista. What I was expecting was that he'd play on either side of a three-man midfield and play an Isco-type role. He can dribble, hold onto the ball - he's given himself plenty of opportunities to show us that, dribbling aimlessly back into our penalty area before finally deciding to pass - but it looks like he depends on having his mates around him to play off.
That's what Pjanic was like at Roma before we forced him into becoming a regista. Why do we buy these types of players and force them deep? Pjanic adapted well but he would have made a better attacking contribution had he been properly utilised.
There are two acceptable types of regista - the creative Pirlo, Xavi Alonso type and the defensive Mascherano, Busquet, Thiago Motta type. Why pick slow, weak, defensively inept players with a short range of passing for this role?
